Arduino LCD Birthday Card 

• Here are the materials you need: 

• Arduino, LCD Display, 10K 
Potentiometer, USB cable, some 
hook-up wires and a solderless 

Step 2 

• First we connect the 5V and the 
Ground to the rails of the 

• Then we add the potentiometer and 
connect it to 5V and Ground.

• Now we add the display and 
connect it to 5V (second pin) and 
Ground (first pin). 

• We connect the third pin of the 
LCD to the "wiper" (middle pin) of 
the potentiometer. 

Step 4 

• Now turn the backlight on! Connect 
the sixteenth pin to Ground and the 
fifteenth pin to 5V. 

• Plug in the USB cable and you 
should see the backlight light up!

• Now it's time to connect the data 
pins! The list that follows is: 
Display Pin -> Arduino Pin 

• 4^12 

• 5-M1 

• 6^ 10 

• 7/8/9/10 = No connection 

• 11 -»7 

• 12^6 

• 13 ^5 and 14^4
